I had a JIRA OnDemand trial instance, with a non-optimal URL. So, when I decided to go for it, I made a backup (zipped xml files; activeobjects.xml and entities.xml), terminated the trial and made a new instance with the desired URL name.
But when I try to restore the backup with JIRA import, after uploading the zip file to the webdav directory, it fails with the message "This archive doesn't contains any valid JIRA Export file".
Was I wrong assuming the backup would be importable?
Is there any way to restore the back I have into the new OnDemand instance?
